Connector socket

Abstract

A connector socket includes a main body having a card slot and a guide hole communicable with the card slot, a metal cover having a guide channel at one side opposite to the guide hole and a downward extended stopper opposite to the card slot, a control bar movably received in the guide channel, and a metal lever located between the metal cover and the main body and held to the metal cover with a hooking plate upwardly projecting from a hole in the metal cover. The metal lever has a first downwardly bent end engaged with an inner end of the control bar to move along with the latter, and a second downwardly bent end engaged with the guide hole on the main body. A rear edge of the metal lever has at least one supporting point in contact with the stopper of the metal cover.

What is claimed is:  
     
       1. A connector socket, comprising a main body, a cover, a control bar, and a lever member; 
       said main body being flatly fixed to a circuit board and being provided at a front side with a horizontally extended card slot, and at one end of a top with a guide hole communicable with said card slot;  
       said cover being removably connected to the top of said main body and being provided at an end opposite to said guide hole of said main body with a guide channel, at a rear side opposite to said card slot of said main body with a downward and then forward bent stopper, and at a predetermined position of a top with an opening;  
       said control bar being movably received in said guide channel of said cover; and  
       said lever member being flatly and transversely located between said cover and said main body and movably held to said cover by a hooking plate provided at a front edge of said lever member to upward project from and abut on said opening on said cover, said lever member including a first downward bent end close to said guide channel of said cover and engaged with an inner end of said control bar to move along with said control bar, and a second downward bent end close to and extended into said guide hole of said main body, said lever member having a rear edge that is so formed that at least one point thereof is in contact with said stopper of said cover to serve as a supporting point for said lever member to pivotally turn about said supporting point relative to said stopper;  
       whereby when said control bar is pushed inward relative to said guide channel, said first bent end of said lever member engaged with said control bar is moved rearward for said at least one supporting point on said rear edge of said lever member to contact with said stopper of said cover and cause said lever member to pivotally turn about said at least one supporting point, bringing said second bent end of said lever member to move forward and push a card in said card slot out of said card slot;  
       said control bar being provided at said inner end with a notch into which said first bent end of said lever member is engaged to prevent said lever member from undesired lateral displacement.  
     
     
       2. The connector socket as claimed in  claim 1 , wherein the cover and lever member are metal. 
     
     
       3. The connector socket as claimed in  claim 1 , wherein said rear edge of said lever member is provided with at least one rearward protruded surface, and with two forward and outward inclined portions. 
     
     
       4. The connector socket as claimed in  claim 3 , wherein said at least one rearward protruded portion of said rear edge of said lever member is a curved edge with said hooking plate being a center of a circle passing through the curved edge. 
     
     
       5. A connector socket, comprising a main body, a cover, a control bar, and a lever member; 
       said main body being flatly fixed to a circuit board and being provided at a front side with a horizontally extended card slot, and at one end of a top with a guide hole communicable with said card slot;  
       said cover being removably connected to the top of said main body and being provided at an end opposite to said guide hole of said main body with a guide channel, at a rear side opposite to said card slot of said main body with a downward and then forward bent stopper, and at a predetermined position of a top with an opening;  
       said control bar being movably received in said guide channel of said cover; and  
       said lever member being flatly and transversely located between said cover and said main body and movably held to said cover by a hooking plate provided at a front edge of said lever member to upward project from and abut on said opening on said cover, said lever member including a first downward bent end close to said guide channel of said cover and engaged with an inner end of said control bar to move along with said control bar, and a second downward bent end close to and extended into said guide hole of said main body, said lever member having a rear edge that is so formed that at least one point thereof is in contact with said stopper of said cover to serve as a supporting point for said lever member to pivotally turn about said supporting point relative to said stopper;  
       whereby when said control bar is pushed inward relative to said guide channel, said first bent end of said lever member engaged with said control bar is moved rearward for said at least one supporting point on said rear edge of said lever member to contact with said stopper of said cover and cause said lever member to pivotally turn about said at least one supporting point, bringing said second bent end of said lever member to move forward and push a card in said card slot out of said card slot;  
       wherein said hooking plate of said lever member is upward and then forward bent to project from said opening on said cover.  
     
     
       6. The connector socket as claimed in  claim 5 , wherein the cover and lever member are metal. 
     
     
       7. The connector socket as claimed in  claim 5 , wherein said rear edge of said lever member is provided with at least one rearward protruded surface, and with two forward and outward inclined portions. 
     
     
       8. The connector socket as claimed in  claim 7 , wherein said at least one rearward protruded portion of said rear edge of said lever member is a curved edge with said hooking plate being a center of a circle passing through the curved edge.
